The utility model discloses production efficiency is high, and the electrical safety performance is superior than other like products.
Description
Technical field
The utility model relates to electric wire field, is specially a kind of not novelly to be with metal sheath flexible fire-proof cable.
Background technology
Flexible fire-proof cable has the time of several years in the development of China, and the different flexible fire-proof cables according to structure can be divided into: metallic sheath series and non metallic sheath series.The high-fire resistance of product such as metallic sheath series main copper strips or steel band etc. can reach " circuit integrality " test request.Flexible fire-proof cable due to metallic sheath series needs to adopt metal tape armour, so make the bending property of cable and flexility greatly reduce.There is another one series thus: non metallic sheath series of flexible fireproof cable.The flexible fire-proof cable of the non metallic sheath series of existing many producers all have employed " silicon rubber insulation " or " the fire-resistant composite band of silicon rubber ".Silicon rubber insulation due to rubber intrinsic, make the physical property itself that insulate poor, and production efficiency is on the low side.And adopt the maximum shortcoming of " the fire-resistant composite band of silicon rubber " wrapped insulating barrier the most can not do water-proofing treatment exactly, easily cause insulation resistance to decline.And the production of above two kinds of flexible fire-proof cables makes efficiency all on the low side due to the restriction of production technology.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of is not novelly with metal sheath flexible fire-proof cable, and adopt ceramic polyolefin as main fireprotection layer, adopt low smoke and zero halogen equipment to extrude continuously to enhance productivity, ceramic polyolefin has 10 in addition
13the insulation resistance of power, solves " the fire-resistant composite band of silicon rubber " and easily to intake the problem causing insulation resistance to reduce.
In order to solve the problem, the technical solution of the utility model is: a kind of novel metal sheath flexible fire-proof cable of not being with comprises copper core conductor, phlogopite fireprotection layer, isolated insulation layer, inorganic fire-retarded gasket for packing, fire-retardant twining package tape, ceramic polyolefin fireprotection layer and low smoke and zero halogen outer jacket, described copper core conductor is positioned at center, phlogopite fireprotection layer and isolated insulation layer form insulated wire cores successively outside, some bar insulation cores are twisted into cable core, inorganic fire-retarded gasket for packing is filled in the middle of cable core, fire-retardant twining package tape, ceramic polyolefin fireprotection layer and low smoke and zero halogen outer jacket are arranged in order outside.
Described copper core conductor is the transmission conductor of cable, and conductor is adopted non-pressing and pressed circular explained hereafter, and conductor electrical performance and mechanical performance meet GB/T3956-2008 " conductor of cable " and specify requirement.
Described phlogopite fireprotection layer, material adopts gold mica tape.Mechanical performance compound GB/T19666-2005 " fire-retardant and fire-resisting cable general rule " the appendix C regulation of gold mica tape.Fluorophologopite before this place adopts phlogopite mainly to substitute, because the toxic gas of the latter's meeting charge releasing belt " fluorine " under flame condition.
Described isolated insulation layer, preferential employing ceramic crosslinked polyolefin insulating material, processing mode is that half extruding is extruded.Also ceramic polyolefine material can be substituted as other option crosslinked polyethylenes.
Described inorganic fire-retarded gasket for packing, have employed high flame retardant glass fibre and adds continuous rope packing material.Due to insulated wire cores in cabling process in the middle of have space, and have oxygen in space can be combustion-supporting.In order to ensure the performance of cable, this inorganic fire-retarded gasket for packing of the fill gaps at cable core center.
Described fire-retardant twining package tape, have employed glass fiber twining package tape.Fire-retardant twining package tape for pricking into some bar insulation cores, and plays fire-retardant effect
Described ceramic polyolefin fireprotection layer, adopts ceramic polyolefin oxygen barrier material material.This layer is main fireprotection layer, and the hull shape that can sinter rapidly ceramic in the flame of ceramic polyolefine material more than 600 DEG C into becomes fireprotection layer, and along with the rising of flame temperature and continuing of burning time, crust effect can be more experienced better.
Described low smoke and zero halogen outer jacket, in order to distinguish the difference with other cables, adopts orange low smoke and zero halogen sheath.Low smoke and zero halogen sheath adopts and squeezes tube process.
Adopt the utility model can reach following effect: the utility model adopts the ceramic polyolefine material of non metallic sheath as main fireprotection layer, and Total Product soft effect is very good.The highest ranking " circuit integrity test " that product can be required by BS6387.After isolated insulation layer adopts up-to-date ceramic polyolefine material to extrude in addition, the water resistance of cable can greatly be enhanced productivity and increase to " the fire-resistant composite band of silicon rubber " relatively on the one hand, and the mechanical performance that " silicon rubber insulation " insulate relatively is on the other hand improved.
